DRYING BRICKS.

Specification of Letters Patent.

Vatelrted Sept. 2,1913.

To LZ/1 l't0/mm, 'it may conce/r11,

lie it known that l, Joins (l. loss, citizen oit' the United States, residing at llllkhart, YIndiana, have invented certain new and usc ful ,lnlprorements in Drying 4Bricks, oit which, the following is a speeitcaton.

My invention hereinailter described, re .lates to the drying` ot bricks, and has, as its object, the more direct or uniform application oit the air current, to the mass ot bricks, and the more direct rcnuwal oit' moisture ab sorbed by the air, so that the moisture, once removed from the mass et' bricks, or any portion o't said mass, will not come again into Contact, with any other part ot said mass. This concerns economy ot heat, and rapid and uniit'orm drying.

Prior to this my invention, the art oit drying bricks has been practised by ruiming cars laden with loosely piled bricks, into tunnels, closed on the sides and top, and at the receiving end, and opening into an exhaust passage, at the other end. This construction contines the drying current, and continues it from the air inlet end to the discharge. But it also includes and continues the moisture, absorbed at the initial and earlierl action, and the drying current becomes less and less eitieetive from beginning to end.

My invention includes in the completed construction, these old cars, ior carrying` the loosely piled brick, the ducts t'or the heated air and the trucks abt'rve the duets, and consists, first, oit a method ot discharoing the air drying current, laterally confined, directly through the mass of bricks, loosely piled on the ear or cars throughout. the length oit the active duct, and directly discharging the moisture laden air into the i tmosphere.

lt consists further in a method of loading and locating` the cars, so as to t'orm a cointinuous series of cars, and continuous mass of bricks :from end to end, in closing the sides and discharging the drying current from the drying air duct, through a coterininous line of piled bricks, directly into the atmosphere.

lt consists 'further in the new and useful construction, whereby these methods are carried on.

l have illustrated these constructions and the method, by the accompanying` drawings, in which,

Figure 1 shows a t'ront viewo't' the drier,

and Fig. 2, a central longitudinal Vertical section. i

ln these drawings the air ducts are shown at it', these beingl dill'creut arrangements ot the ducts, as hereinafter explained. 'lhesc ducts extend the entire length oi the, Atrack and are closed at the sides and ends, and hare oienings upward only, so as to direct the drying current upward through the masses ot brick placed above them. 'Ihe air in the ducts is heated in any approved way. .fis shown, steam pipes or coils 2 are located in the ducts, and in these waste steam may be utilized. flfhese pipes or coils are, :lor the best etl'ect, eoextensive with the ducts. its shown at, A, the duet located directly beneath the trackway il, on which run the brick carrying ears, represented at /lv. These cars are steel trucks (about 7 :lieet long) being mounted on wheels, adapted to run on rails in the channel between the ducts A or over the duct; or ducts il, itt' the latter are used.

lhe direct support 'tor the bricks consists o i a pallet itormed as a trame, in which, as shown 2xt wood scantling 5 are laid across the top, or plattform ot the truck, in nun1- ber sulllcient to sustain the strips or slats o secured thereon. lhese slats are at least as wide as the thickness of a brick, and are laid about three lourths ot an inch apart. flhfe'terably the lirst two courses o't the brick are piled lengthwise ot the slats, itaced two deep, and the third and all sueeiaaling courses are alternately laid crosswise, but all with spaces ot about three Vlourths oit an inch between bricks, so that there are continuous air passages irom bottom to top througlmut the entire mass of bricks. It will be iuulerstood that this wooden 'trame or brick supporting pallet is made wider than the ear truck and extends on each side, over 'he edge of the tlat top oit the duct, when the duct A is used, and over the {iattop oit an intermmliate extension oit the base tas at (l) when the duct ik, is used. The parts are so m'oportioned that the lateral edge oit' the pallet mores as close to said tlat top surlaee as practicable, on the entrance oit the car, as indicated at 7. This allows the side curtains to tit closely upon said surface, and any suitable means may he used to make, at that edge, a close joint. The pallet extends at `.ach end, so that the end ot the pallet on one car will abut against the end o't Athe next. succeeding car, and make a co11- tinuous platform, and the bricks are piled flush With the lateral end and edges of the pallets, so that, When in place the bricks of all the trucks torni a continuous line or column, and are acted on as one body, throughout the entire length. The curtains therefore are' necessary only at the sides and extreme ends of the entire column of brick laden trucks, and not at the ends of each truck. T hey are made practically continuous on all sides, and are made of any material suitable tor the conditions. rlChey are suspended by chains or ropes, as indicated at 7, or in any suitable Way, movable toward and from the sides, and are held close to the surfaces to be covered, by Wedges or any equivalent means. rlf'hetop of the Whole column of brick laden trucks is open for the tree escape tothe atmosphere, of the moist air as it rises from the massief bricks, throughout the entire length ot the column.

T he ducts when provided With interior heating appliances, are open at both ends, for the admission of air, in proper amount. When the chiots are located directly beneath the tracks, openings at proper intervals are made in the topot the arch, as shown at S, of tour inches in diameter. But when the ducts A are used, similar air passages 8 are made in the side Wall of the duct. In both cases the. dry air from the duct is discharged into the closed space beneath the piled bricks and is free to risc up through the mass. It Will be understood that suitable means may be used to give torce to the air and to drive it through the interstices of the mass of bricks. But this torce is less for the reason that the air is held in by the curtain, no lateral eddies are possible, and there is tree escape from the top. Further,

the heatJ is economized and the draft ulti-Y mately increased, as the mass ot green bricks is a good conductor of heat, and thus heat by conduction as Well as by convection is carried from bottom to top; ln Vthis arrangement. no draft chimney is needed. I

prefer the elevated ducts A with the lateral discharge openings, since in this construction the openings are not liable to 'be clogged.

rlhe operation, indicated in the above description, is simple. The bricks pled'on the truck platform at Vthe machine, are flush with said platform on all sides, and as the the uncovered top, carrying the eliminatedV moisture directly intoV the atmosphere. As

the curtain is continuous andV4 close ontheV sides and ends there canbe no eddies or disturbing currents, the'drying vagent is drectly and evenly applied to lthe mass of brick throughout, and the greater heat originated at the bottom is conducted up-` ward by the bricks themselves.

I claim as my invention, substantially as Y described An apparatus for drying brick comprising a track and side Walls forming anopentopped trackchannel, said side Walls having flat tops, trucks adapted v to run on said track Within said channel, and having permanently attached platforms withV their sides overlapping and in close proximity to the flat tops or' the Walls, curtains adapted to cover the vertical surfaces of the loads on the truck, and air ducts'tor supplying heatedai-r to said track channels, substantially as described. n

ln testimony whereof, l aliix my signature in presence 4ot two Witnesses. v
